I don't think the original needs editing; it is perfectly clear.
a universe = (the observer/the measurer) + (the rest of the universe)
Before Feynman's era, people were unaware of that they themselves are the part of the universe and thought (the rest of the universe) has an independent existence. That is, their formula is:
a universe = the rest of the universe (or " the universe without them")
We know:
The rest of the universe = (what is being measured) (the observer/the measurer measures what is being measured)
So, the author should have said "but depends on the observer/the measurer", not "but depends on the rest of the universe/what is being measured".
Now, what is your opinion?
